I'm going to use the autotune feature of Microsquirt to set my fuel map (VE table). This system will automatically adjust the VE to achieve the mixture as defined by the target AFR table.
This is a 12x12 table. The Y axis is MAP reading (load), and the X axis is RPM. This table was auto-generated by this microsquirt calculator. What do you guys think? Is this a solid target AFR table or are adjustments needed? |

Are you looking for max power or max economy? For basic all around use that is just about where you want it. (IMG:style_emoticons/default/smile.gif)
If the o2 sensor is responsible for most/all of the A/F measurements ....... make sure there are absolutely zero exhaust leaks before the o2 sensor. |

Are you looking for max power Yes QUOTE or max economy? Yes! QUOTE For basic all around use that is just about where you want it. (IMG:style_emoticons/default/smile.gif) This is really my goal. I might buy some dyno time at some point to squeeze a little more power out. QUOTE If the o2 sensor is responsible for most/all of the A/F measurements ....... make sure there are absolutely zero exhaust leaks before the o2 sensor. Hm...I believe I have no exhaust leaks...is there a way to check besides listening? Whenever i've heard exhaust leaks they have been obvious to me. If I put my foot over my tailpipe while the car is idling, the engine loads up and I don't hear any obvious leaks. I'll make sure to warm up the engine/exhaust before doing the tuning to get everything expanded. |
